12x3 Gym
12x3 is a proper boxing club, for all-comers not just fighters.
With real coaching and conditioning methods – from elite-level boxers and coaches – 12x3 prioritises six key areas of training: speed, stamina, strength, footwork, timing and mindset – to provide an invigorating total-body workout in less than an hour.
Choose from four intense workouts:
- Gloves On: a non-contact, total workout including bag work, drills and circuits. With 12x3 rounds, this is the complete package.
- Gloves Off: a pure strength and fitness class based on a boxer's training plan. No gloves, just hard work and dedication.
- Ring Craft: an old-school boxing coaching class, for those that want to develop as a boxer. Be prepared for light contact.
- Personal Coaching: make the most of your time at 12x3 with a tailored boxing and fitness programme delivered by your own personal coach.
"12x3 have taken the boxing trend up a notch, offering gruelling boxing classes with former boxers".
